Why Your Garage Door Went ‘Off the Rails’

Garage doors might not seem complicated at first glance, but they’re actually quite sophisticated. Despite their size and weight, they operate with a surprisingly simple system that allows them to open and close smoothly on a daily basis.

The design of a garage door is unique—it uses hinged panels that roll up and down rather than swinging open like a regular door. This rolling mechanism relies on a combination of springs, tracks, and rollers to function properly. The spring helps balance the weight of the door, while the rollers move along the tracks to keep the door aligned and stable during operation.

Although the system is simple, each component plays a crucial role. If one part fails, it can cause the entire system to malfunction. That’s why it's important to understand what could go wrong and how to prevent it.

Why Your Rollers Might Come Off Their Tracks

If your garage door rolls off its track, it’s usually due to an issue with one of the key components. Here are the most common reasons why this happens:

1. The Roller Tracks Go Out of Alignment

Over time, the roller tracks can become misaligned, especially if the installation wasn’t done correctly. This misalignment can cause the rollers to pop out of place, making the door difficult or impossible to operate.

2. A Lift Cable Stretched or Broke

The lift cables help transfer the tension from the torsion spring to the door. If one of these cables stretches or breaks, it can throw off the balance of the door, leading to uneven movement and potential derailment of the rollers.

3. A Roller Wears Out

Rollers are subjected to constant motion, which means they can wear down over time. If one roller fails, the remaining ones may have to work harder, leading to added stress and possible misalignment of the tracks.

While knowing the cause of the problem won’t fix it on its own, it can help you identify early signs of trouble.
